RELATED APPLICATIONS

This application is the National Stage of International Patent Application No. PCT/US2015/057564, filed Oct. 27, 2015, which claims the priority benefit with regard to all common subject matter of earlier-filed U.S. Provisional Patent Application Ser. No. 62/069,005 filed on Oct. 27, 2014 and entitled “COMPUTER PROGRAM, SYSTEM, AND METHOD FOR OBSERVATION AND COMMUNICATION FOR MOBILE SETTINGS, MOBILE APPLICATIONS, AND WEARABLE MOBILE DEVICES”, each of which is hereby incorporated by reference in its entirety into the present application.

BACKGROUND

Usability testing and analysis is an empirical method of measuring a product's ease of use with prospective end users. For software or website usability analysis, usability researchers typically use custom software tools to gather information such as time spent on a task, mouse clicks, keyboard inputs, and subjective comments from end users. Programs for desktop computer usability research include Morae™, Camtasia™, Surflogger™ and other programs. Conventional webcams are also used to monitor user behavior and capture user comments. These tools are not, however, suitable for performing usability research of the use of products in mobile settings, mobile devices such as smartphones, wearable mobile devices, and other products. For example, conventional webcams are difficult to use and/or attach to wearable mobile devices and are unable to capture information from the user's point of view. Thus, usability research of products in mobile settings, mobile devices, and wearable mobile devices is more difficult using presently-available technology.

The above-described devices 12, 14, 16 may communicate over a wired or wireless network 32 such as the Internet, an intranet, “wifi” connection, cellular network (e.g., 3G or 4G), near field communication (NFC) technology, Bluetooth®, hotspot, direct wifi, HDMI, or similar communications networks.

Turning to FIGS. 3-5, the application will now be described in more detail. The application may be used in three modes: wearer mode, on-site observer mode, and remote observer mode.

In a wearer mode, the application (on the first wearable mobile device 12) may instruct the camera 20 to capture first-person video, as shown in block 100 of FIG. 3. For example, the first-person video may be footage of the wearer of the first wearable mobile device 12 performing a task from the wearer's point of view such as opening a package (see FIG. 1).

The application on the first wearable mobile device 12 may then instruct the transceiver of the first wearable mobile device 12 to transmit the first-person video to the second wearable mobile device 14 of the on-site observer and/or the remote mobile device 16 of the remote observer via the network 32, as shown in block 102. In this way, the on-site observer and/or the remote observer may view the first-person video in real time.

The application on the first wearable mobile device 12 may also receive instructions, messages, or other communications from the second wearable mobile device 14 and/or the remote mobile device 16 of the remote observer via the network 32, as shown in block 104. The messages may be Short Message Service (SMS) text messages, emails, or the like. For example, the application may receive a text message from the on-site observer asking the wearer of the first wearable mobile device 12 if he is familiar with the task he is being asked to perform.

The application on the first wearable mobile device 12 may then instruct the display 22 to display the instructions, messages, or other communications on the first wearable mobile device 12, as shown in block 106. For instance, the instructions may request that the wearer of the first wearable mobile device 12 perform a particular action (e.g., open the package shown in FIG. 1). In this way, the wearer of the first wearable mobile device 12 may communicate with the on-site observer and the remote observer while performing the task, as described above.

In an on-site observer mode, the application (on the second wearable mobile device 14) may instruct the camera of the second wearable mobile device 14 to capture third-person video from the perspective of the on-site observer of the wearer of the first wearable mobile device 12 performing the above action, via the camera of the second wearable mobile device 14, as shown in block 200 of FIG. 4. That is, the third-person video may include footage of the wearer of the first wearable mobile device 12 performing the above action, thus capturing visual data that the first-person video generated by the first wearable mobile device 12 may not have captured.

The application on the second wearable mobile device 14 may then instruct the transceiver of the second wearable mobile device 14 to transmit the third-person video to the remote mobile device 16 of the remote observer via the network 32, as shown in block 202. In this way, the remote observer may view and/or manipulate the third-person video via the mobile device 16.

The application on the second wearable mobile device 14 may also receive instructions, messages, or other communications (e.g., SMS text messages or emails) from the remote mobile device 16 of the remote observer via the network 32, as shown in block 204. For example, a received text message could be a request for the on-site observer to ask the wearer of the first wearable mobile device 12 a specific question or to instruct the wearer of the first wearable mobile device 12 to perform an action. In this way, the remote observer or another user may interact with the wearer of the first wearable mobile device 12 as if he was present (e.g., on-site).

The application on the second wearable mobile device 14 may notify the on-site observer of incoming messages by instructing the second wearable mobile device 14 to vibrate, play a sound, display an image, or present an alert, as shown in block 206. For example, the second wearable mobile device 14 may display an alert that the remote observer has sent a text message to the on-site observer.

The application on the second wearable mobile device 14 may then instruct the display of the second wearable mobile device 14 to display the messages for the on-site observer to view, as shown in block 208. The application may automatically display the text message on the display of the second wearable mobile device 14 along with the alert.

The application on the second wearable mobile device 14 may standby (i.e., “listen”) for an input from the on-site observer such as the on-site observer tapping on the second wearable mobile device 14, as shown in block 210. The application may also standby for an input received via a button, knob, switch, proximity sensor, pressure sensor, accelerometer, or other component of the second wearable mobile device 14.

The application on the second wearable mobile device 14 may then detect any input such as the tap in block 210, as shown in block 212. For example, the application may detect the on-site observer's tap via its vibration sensor or proximity sensor.

The application on the second wearable mobile device 14 may log, flag, or mark the video or create a time stamp at the moment of detecting the input, as shown in block 214. The time stamp may represent a point or event of interest or a useful reference point. The time stamp may be recorded in a log file and the flag (e.g., tap label) may be inserted into the video file at the end of the recording. In this way, the observers can later jump to the flagged points or events of interest on the video when reviewing the video at a later time. The first-person video and the third-person video may be synchronized so that the observers may view the two or more corresponding videos at the same time.

In remote observer mode, the application (on the remote mobile device 16 of the remote observer) may receive the first-person video from the first wearable mobile device 12 and/or the third-person video from the second wearable mobile device 14 via the network 32, as shown in block 300 of FIG. 5. The IP address of the first wearable mobile device 12 may be appended to the video or video feed for the application on the remote mobile device 16 to play the video or video feed.

The application on the remote mobile device 16 may standby (i.e., “listen”) for inputs such as a text entry or a spoken prompt from the remote observer, as shown in block 302. For example, the text entry can be the request for the on-site observer to ask the specific question to the wearer of the first wearable mobile device 12, as described above. The application on the remote mobile device 16 may also standby for an input received via a button, knob, switch, proximity sensor, pressure sensor, accelerometer, or other component of the remote mobile device 16.

The application on the remote mobile device 16 may then transmit the text entry as a text message to the second wearable mobile device 14 via the network 32, as shown in block 304. Text messages sent this way may be archived or saved. In this way, the remote observer may communicate with the wearer of the first wearable mobile device 12 and the on-site observer while documenting the conversation.

The first-person video, third-person video, text messages, and other data and information may be recorded and stored in a memory of the first or second wearable mobile devices 12, 14, the remote mobile device 16, and/or any other computing device connected via the network 32 for later review. The log file may be stored with the videos so that application may selectively shift to the events of interest or reference points when the recordings of the videos are watched.

The present invention provides many advantages and benefits. For example, the present invention allows a wearable mobile device wearer and an on-site observer to see from the wearer's perspective at virtually the same time. The present invention captures more useful video footage particularly in usability testing of products in mobile settings. The on-site observer can also easily log an event of interest by touching a button or stem on his or her wearable mobile device. The present invention eliminates the need for an extra person to operate an on-site observation camera. The application allows the on-site observer to communicate via text message chats in a head-mounted display in his line of sight instead of switching between observing the wearer and communicating via the text messages. The present invention also allows the video to be analyzed without specialized software. The present invention can also be used in many fields such as teleconferencing, medical settings, professional settings, agriculture, and other settings.

In another embodiment of the present invention, the first wearable mobile device 12 may be mounted on an object being tested or an observation object instead of a wearer. For example, the first wearable mobile device 12 may be mounted on a vehicle, robot, crane, helmet, weapon, drone, or extension device such as a cable, extension arm, boom, or any other device for providing a first-person view from the perspective of the object. In this way, the on-site observer and the remote observer can perform visual research from the object's point of view as the object moves and/or operates.
